Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] refer to Figure 1 to Figure 3 ,like Figure 1 to Figure 3 As shown, a wireless channel allocation method includes: base station action: in a wireless communication system, a large-scale offline node moves quickly to the vicinity of a fixed base station, and when a burst request accesses the base station, the base station broadcasts a BEACON message, and the node sends a BEACON message according to the BEACON message Access request: the base station judges the competition intensity according to the competition situation of the nodes in the dense node group for the channel, determines the ch...

Abstract

The invention discloses a wireless channel allocation method, which relates to wireless channel allocation technology, including: base station action: in a wireless communication system, a large-scale offline node quickly moves to the vicinity of a fixed base station, and when a burst request accesses the base station, the base station broadcasts a BEACON message, the node sends an access request according to the BEACON message; the base station judges the competition intensity according to the competition situation of the nodes in the dense node group for the channel, determines the channel competition mode, and notifies the node; node action: the node synchronizes the competition mode, reserves the service channel; After success, complete the communication on the designated service channel; release the occupied channel after the node communication ends; improve the utilization rate of the service channel. The method of the invention effectively solves the problem that high-speed dense node groups cannot access service channels in time due to high node density and fast movement speed, and the fixed base station has the ability to work simultaneously on CCH and SCH multiple channels.

Description

technical field [0001] The invention relates to a wireless channel allocation technology, in particular to a wireless channel allocation method for fast mobile dense node groups bursting into a fixed base station. Background technique [0002] At present, with the large-scale increase of wireless mobile nodes and the increasing demand for accessing the network during the movement process, in a specific scenario, a group of fast-moving dense nodes is required to burst into a fixed base station. Come to great challenge. The traditional method cannot meet the real-time requirements of nodes accessing the base station. An efficient wireless channel allocation method for fast mobile dense node groups bursting access to fixed base stations is of great significance for fast mobile node networking and access to wireless base stations. It can not only improve timeliness and improve service channel utilization, but also can Improve communication efficiency. [0003] The channel all...
